Paddy field yield per mu
Under general planting conditions, the yield of rice per mu is about 2000-2400 Jin. It should be noted that the specific yield per mu will be affected by different regions, different environments, different climates, different varieties and other factors. These elements will lead to different yields. Good varieties are usually used, and under scientific management, rice is easy to yield.
Rice field planting prospect
The cost of rice planting includes land rent, seed cost, pesticide cost, fertilizer cost, labor cost and some equipment to assist planting. Total cost1around 500 yuan. If the yield per mu is 1600 kg, the income per mu is 2400 yuan. Excluding the planting cost, one acre is 900 yuan.
The economic benefit of rice is not high, but there is a great demand for rice in China. Now the planting area is decreasing, and China needs to import a large amount of rice from abroad every year, which raises the price of rice to some extent. In this case, there is still a certain planting prospect.
How to plant rice fields for high yield?
1, planting time
Because the climatic conditions vary greatly from place to place, the specific sowing and harvesting time of rice is also slightly different. Generally speaking, rice can be sown when the local daily average temperature is stable above 12 degrees for 3 to 5 consecutive days, and rice cannot be sown when the temperature is lower than 10 degrees.
2. Seed treatment
Select excellent varieties with strong disease resistance, good stress resistance, high purity, high germination rate, high yield, strong germination potential, full seeds and healthy fullness. Before sowing rice, choose sunny days from 10 to 3: 00 pm, expose to the sun for 2 to 3 days, and then soak in clear water to accelerate germination.
3. Land consolidation
Rice is suitable for planting in deep, loose and fertile soil with good drainage, and the planting area should be deeply plowed 15-25 cm in advance to create a good rhizosphere environment for rice growth and development.
4, intertillage weeding
One week after rice transplanting, the first intertillage weeding should be carried out. For plots with more weeds, herbicides should be sprayed for closed weeding in the field. Commonly used herbicides include mesotrione, bensulfuron-methyl, cyhalofop-methyl, bensulfuron-methyl, penoxsulam, bentazon, dimethyl carbon tetrachloride and so on.
5. Strengthen pest control.
The common diseases and insect pests in rice growth are damping off, cotton rot, sheath blight, rice blast, stem borer, rice leaf roller, stem borer, rice thrips and rice planthopper. Everyone should strengthen field inspection and carry out targeted prevention and control according to the types of pests and diseases at the early stage of the disease.
